Get-Property will crash because it did not evaluate to a valid getter

    tvm - 2023-04-24

    On one of my projects, someone connected to the web visu and caused the PLC to crash.

    I can see a message in the logs: "Get-Property will crash because it did not evaluate to a valid getter. Is there an inbetween null value in nested properties?." But I haven't been able to reproduce it, so I don't know which visu or element is causing it.

    I've seen this error before, when trying to use the visu text editor element while "Activate property handling in all elements properties" is checked in the Project Settings. This is apparently a known issue in the Schneider Machine Expert implementation of Codesys.

    So far Schneider tech support hasn't been able to answer questions about it. Where could I find information about this error? Knowing that it might be connected to the text editor element (which I'm not using in my project), are there other elements that use the same underlying code that might cause this?
